How to pass large number of parameters to a constructor?

I am having a main form named "add.cs" containing user information (its name , age ....etc.) on this form i have drag a button to add the user's children information (their name , blood group , date of birth..etc)whose click event opens a form "addchild.cs" on which i have dragged two button one for stroring data and another to add controls at runtime. To add controls at runtime i have used this coding

privatevoid button1_Click(object sender,EventArgs e){try{
                childrenCount++;Label lblchild =newLabel();
                lblchild.BorderStyle=BorderStyle.Fixed3D;
                lblchild.Location=newPoint(20,(childrenCount -1)*50);
                lblchild.Size=newSystem.Drawing.Size(50,20);
                lblchild.Text="Child  "+(childrenCount -1);TextBox tName =newTextBox();//TextBox for the name
                tName.BorderStyle=BorderStyle.Fixed3D;
                tName.Location=newPoint(120,(childrenCount -1)*50);
                tName.Size=newSystem.Drawing.Size(135,60);
                tName.Text="";DateTimePicker calendar =newDateTimePicker();//MonthCalendar calendar = new MonthCalendar(); //Calendar to choose the birth date
                calendar.Location=newPoint(310,(childrenCount -1)*50);ComboBox bloodGroup =newComboBox();//ComboBox for the blood group
                bloodGroup.Location=newPoint(650,(childrenCount -1)*50);
                bloodGroup.Size=newSystem.Drawing.Size(135,60);for(Enum.Blood_Group l =Enum.Blood_Group.O_negative; l <=Enum.Blood_Group.AB_positive; l++){
                    bloodGroup.Items.Add(l);}this.panel1.Controls.Add(lblchild);this.panel1.Controls.Add(tName);this.panel1.Controls.Add(calendar);this.panel1.Controls.Add(bloodGroup);}catch(Exception ex){MessageBox.Show(ex.Message);}}

Now I have created a separate external class named "Childrendata" for storing the value of controls added on " addchild.cs". These class contains all the data that i want to store.

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks; namespace Jain_milan
{class Childrendata
    {string childname, childblood, childbirth; publicstring Childbirth
        {get { return childbirth; }set { childbirth = value; }
        } publicstring Childblood
        {get { return childblood; }set { childblood = value; }
        } publicstring Childname
        {get { return childname; }set { childname = value; }
        } 
    }
} 

then on the click event of the submission button on addchild.cs i have 
used this code to store the controls data to the variables of external 
class called Childdata.cs.

privatevoid submitbtn_Click(object sender, EventArgs e)
        {//Checks the valuestry
            {string message = "";foreach (Control c inthis.Controls)
                { //loop throught the elements of the formif (c.GetType() == typeof(Panel))
                    { //check if the control is a Panel//Get the values from the input fields and add it to the message string                        Panel panel1 = (Panel)c;
                        Label lblchild = (Label)(c.Controls[0]);
                        TextBox tName = (TextBox)(c.Controls[1]);
                        DateTimePicker calendar = (DateTimePicker)(c.Controls[2]);
                        ComboBox bloodGroup = (ComboBox)(c.Controls[3]); //add to class                        Childrendata childdata=new Childrendata();
                        childdata.Childname = tName.Text;
                        childdata.Childblood= bloodGroup.Text;
                        childdata.Childbirth=calendar.Text; 

                    }
                }
            }
 catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
         }

Now how can i made the constructor taking array or any other 
thing as parameter and that store all the values and i can call this 
constructor to my main page named add.cs .So on click event of a button 
on add.cs i may store these values into database by using coding like this.

Childrendata cd = new Childremdata();
Children child = new Children(); 
                    child.Namechild = cd.Childname;
                    child.Bloodchild = cd.Childblood;
                    child.Dobchild = cd.Childbirth;if (new InsertAction().Insertchildren(child))
                    {
                        MessageBox.Show(" Children Insertion Happen ");
                    }else
                    {
                        MessageBox.Show(" Children Insertion does not Happen ");
                    }">

Please tell me the exact example because i have tried a-lot to solve this but no output!! Please help please please please
